Hello,
This is a beginer's question. In Siemens S7-300, A, AN, O, and ON are used to organize the logical relationship of the relay inputs, but I can not find the similar instructions from AB's SLC 500 instruction set. The examples in their manual doesn not contain any source code in text. All the design is represented as ladder diagram.
I wonder if SLC 500 only use software RSLogix 500 to translate the ladder diagram input by the user to the machine code automatically, so user doesn't need to know the text version of the instructions?
